GRAIN SHOCKER.

Application filed March 12, 1927.

The object of this invention is to provide a grain shocker which may beattached to any standard grain binder in position to receive the bundlesof grain as they pass from the binder deck, and may be easily operatedto gather the bundles into a shock and then deposit the shock upon theground with their heads uppermost. The invention seeks especiaily toprovide a shocker which will be m simple in construction and operationand easily manipulated by the driver from the seat of the binder andwhich, when attached to the binder, will not add perceptibly to thedraft. These stated objects of the invention, and other objects whichwill incidentally appear in the course of the following description, areattained in such an apparatus as is illustrated in the accompanyingdrawings, and the invention resides in certain 2() novel features whchwill be particularly pointed out in the appended claims.

In the drawings: Figure 1 is a perspective view of a shocker embodyingmy invention, the shocker being shown in its proper relation to abinder, a portion of which is indicated in dotted lines; Fig. 2 is aside elevation of the shocker showing the same in an intermediateposition as the shock is being transferred to the ground;

Fig. 3 is a similar View showing the shocker in position to release theshock;

Figs. 4 and 5 are detail elevations showing different positions of theshock-engaging fingers;

Fig. 6 is a detail section, and Fig. 7 is a transverse section on theline 77 of Fig. 2.

In carrying out the invention, I provide a main frame, indicated at 1,which may be of any suitable form and is illustrated as consisting ofparallel side rails connected by a cross bar at their front ends, thespace between the rear ends of the side bars or rails being left openfor the passage of the shock. The outer rail 1 is equipped with a caster2 whereby it may be supported for ready travel over the field and to theinner side rail are secured beams 3 which are hingedly connected, asindicated at 4, to the said rails and extend to the binder frame towhich they are secured firmly in any convenient or preferred manner.Braces 5 may be provided to reinforce these attaching arms, as will beunderstood. Near the rear ends of the side rails 1 a cranked rock shaftor arch Serial No. 174,799.

6 is journaled therein, the greater portion of the length of said shaftbeing formed into the arch 7 and adapted to carry a supplemental frame 8while the ends of the shaft are formed into cranks 9 which are disposedsubstantially at a right angle to the sides of the arch and to which areattached the rear ends of tension springs 10 which have their front endsattached to screws 11 mounted in brackets 12 at the front ends of theside rails whereby the tension of the springs may be easily regulated.Secured to and extending between the side rails are a series of bars orrods 13 which are in the form of inverted arches and define arcs, theradii of which increase successively from the rear to the front of theframe, these bars or rods forming a cradle to receive the bundlespassing from the deck of the binder. The butts of the bundles will bedirected toward the front, and a guard 14 of any suitable form may besecured to thefront cross bar of the main frame so as to prevent thebundles slipping from the cradle.

The supplemental frame comprises two side bars, preferably of flat metalconstruction, connected at their front and rear ends by cross bars 15 ofsimilar form. The arch 7 is journaled in the side bars of the frame 8 atabout the center thereof and bearing brackets 16 are preferably securedto the side bars so as to provide an additional support for the arch toprevent bending of the same under the strains to which it is subjectedin use. Adjacent the centers of the cross bars 15 and at opposite sidesof the center and equi-distant therefrom, frame bars 17 are securedthereto and extend longitudinally of the frame above the arch. Theextremities of these frame bars 17 are turned (.lownwardly, as shown at18, to provide supports for carrying rods 19, and upon these carryingrods are loosely mounted heads 20 carrying the shock-engaging andclasping fingers 21. Each head 20 is provided with a laterally extendinglug 22 and a retractile spring 23 is attached at its opposite ends tothe said lug and to the immediately adjacent frame bar 17, as shown inFig. 1 and as will be understood. Upon reference to Figs. 2 and 3, itwill be noted that the fingers 21 define arcs of different radii, thefingers having the shortest radii being disposed at that end of thesupplemental frame or shock carrier which is at the rear in the positionassumed when the shock is being raised. This formation adapts thefingers to the tapered form of the shock and maintains that form as theshock is being transferred from the cradle to the ground, the pressureexerted by the fingers serving to bind the bundles into a shock of atapered or substantially conical form so that the butts will be spreadand the heads brought together to cause the shock to stand upri ht onthe ground without the necessity of additional securing devices.Attached to each head 20 at a point at the rear of the arch 7 is arocking arm 2% which is fitted about the respective fulcrum rod 19, asindicated at 25, whereby it may be rocked on said rod, and above the rodthe arm is shaped to extend outwardly and then upwardly, as clearlyshown in Fig. 7. To the upper end of each arm 24 is pivoted one end of alink 26, the two links being pivoted together, as indicated at 27,whereby the links and arms together constitute toggles disposed atopposite sides of the center longitudinal plane of the supplementalframe or carrier. At a point in advance of the vertical plane of thetoggles, a rod 28 is secured upon and extends between the frame bars 17and between said frame bars a guide roller or pulley 29 is rotatablymounted thereon, a cable 30 being attached at one end to the pivot- 27of the links 26 and extending thence to and about the roller 29 and thento the front of the machine where it may be trained through any suitableguides to a point adjacent the drivers seat. The heads 20 are rotatableand also slidable upon the fulcrum rods 19, and it will be seen thatwith the carrier frame in the position shown in Fig. 1 and thetoggles inthe position shown in full lines in Fig. 7 a pull exerted upon the cablewill cause the pivot 27 to move dowi'iwardly in a straight line so thatthe .lower ends of the links 26 will move outwardly and spread apart,the arms 2 lbeing thereby rocked about the rods 19 so that the fingers21 will be swung together to clasp the shock, the position of thefingers after this 'move-ment being indicated by dotted lines in Fig. 7.To maintain the lingers in shoclcengaging position, the free end of thecable may be secured in any obvious manner adjacent the drivers seat,but it will be observed that, when the fingers are fully closed, thepivot of the links 26 will be below a line passing through the upperends of the arms 2st and, therefore, the end of the cable may be leftfree, provided care l e observed to so support that it will not drop tothe ground or be carried to a point where it cannot be convenientlyreached for a sub sequent operation.

Disposed about the rear ends of the fulcrum rods between the lugs 18 andthe adjacent ends of the heads 20 are expansion springs 31 which tendconstantly to maintain the heads in the forward or lowered positionillustrated in Figs. 1, 2 and 4:. EX- tending between the rear ends ofthe heads 20 is a loop 32 shown most clearly in Fig. 6 in which isengaged one end of a link 33 which has its other end pivotally attachedto an angle arm or striker 8%, said angle arm or striker being hun uponthe rod 28 and being so disposed as to extend across the path of thelinks 26. Mounted upon the front cross bar of the main frame is a rockshaft 35 from which rises a lever or crank arm 36 in the centrallongitudinal plane of the apparatus and to the said crank arm at theupper extremity thereof and at av point below its extremity,respectively, are pivoted connecting rods or links 37 and 38, the link37 being pivotally engaged about the arch 7 and the link 38 beingengaged about the rod 28 in a similar manner. The rock shaft 35 extendsto a point over the binder frame where it may be conveniently reached bythe driver and is equipped with a crank or pedal, indicated at 39.

In operation, the machine will travel over the field at the stubble sideof the binder and will be disposed so that the delivery edge of thebinder deck is immediately over the cradle. The bundles will pass fromthe binder deck into the cradle and will be permitted to collectthereinuntil enough bundles have been formed to make a shock, thecarrier frame and shock-engaging fingers be ing, during this period,supported substantially in the position shown in Fig. 2 with thefingers, however, spread apart, as shown in full lines in Fig. 7. Whenenough bundles have been collected to form a shock, the shaft 35 isactuated to swing the lever or crank arm 36 forward, thereby causing thecarrier frame to move forward and the arch 7 to rock about the shaft 6as a center, the cranks 9 being simultaneously swung rearwardly and thesprings 10 put under increased tension. lVhen the carrier orsupplemental frame has been thus brought to a position directly over thecollected bundles, a pull is exerted upon the cable 30 and the togglesthereby folded and swung into the positions illustrated by the dottedlines in Fig. 7 bringing the fingers 21 into position about the shockand compressing the bundles so that they will be firmly held by saidfingers. This movement of the fingers will swing the lugs 22 downwardlyso that the springs 23 will be placed under increased tension but theywill be inactive inasmuch as the pivot 27 will be past the lineconnecting the pivotal connections of the. links and the arms 24. Inother words, the links are on a dead cent-er and will not move unless apositive actuating force is applied thereto. The shock having beenengaged by the fingers 21, the pivot or crank 39 is permitted to swingrea-rwardly so that the springs 10 will be free to act and swing thecranks 9 forwardly, thereby rocking the arch 7 upwardly and rearwardlyso that the shock will be lifted from the cradle and carried to a pointin rear of the same. The lever 36, of course, will simultaneously swingrearwardly and through the connections of the links or rods 37 and 38will swing the carrier frame from the substantially horizontal positionshown in Figs. 1 and 2 to the vertical position shown in Figs. 3, 4 and5. The shock will thus be turned from a horizontal position to avertical position with its butts presented to the ground and the turningof the arch 7 will be continued until the shoe: strikes the ground andfor an instant after the contact of the shock with the ground, theweight of the carrier and the shock causing the arch to swingrearwa-rdly and downwardly after the springs 10 have contracted to theirshort est dimension. The impact of the shock upon the ground will betransmitted to the fingers 21 and through the same to the heads 20 sothat the heads will move upwardly relative to the frame bars 17 and thesprings 31 will be thereby placed under compression. This relativeupward movement of the heads will be sufficientto release the fingersfrom the shock but will not effect opening of the fingers. The upwardmovement of the heads, however, will be transmitted through the link 33to the striker 34 and will cause the striker to impinge against thepivotally connected ends of the links 26 and move them sufiiciently tocarry them beyond the line passing through the connections of the linksto the arms 24, whereupon the springs 23 will at once contract andreturn the parts to the positions illustrated by the full lines in Fig.7. The fingers will then be entirely free of the shock and the springs10 wiil actuate the arch 7 through the cranks 9 to return the carrierfrom the position shown in Fig. 3 to that shown in Fig. 2, the driverpressing upon the pedal 39 so as to effect the desired turning of thecarrier or supplemental frame about the arch, as will be understood.

From the foregoing description, taken in connection with theaccompanying drawings, it will be seen that I have provided a verysimple mechanism whereby the bundles of grain may be quickly gatheredinto a shock and deposited'upon the ground at the rear of the machine asthe machine is drawn over the field. The mechanism is free ofcomplicated arrangements and eliminates unnecessary parts so that it maybe readily connected to any type of grain binder without addingperceptibly to the draft of the machine. The operation of the shocker isat all times under the complete control of the driver of the machine sothat the likelihood of premature or delayed operation of the gatheringfingers and removal of the shock is overcome. The shock-engaging fingersare constructed of resilient metal so that it will not be necessary fora specified number of bundles to be collected in order to form a shockas, within reasonable limits, the fingers will automatically conform tothe diameter of the shock, the ends of the fingers overlappingsufficiently to accommodate spreading due to a. shock containing one ormore bundles more than the average while the curvature of the fingers issuch that they will firmly engage a shock containing a fewer number ofbundles.
